abstract = "The research aims to analyze the runoff in the urban area of Santa
Maria (RS), using the curve number model, developed by the Soil
Conservation Service (SCS) with help of geoprocessing techniques.
This methodology is based on integrated analysis of information
regarding to land use and land cover, reclassified types of soil
according to hydrologic groups proposed by SCS. The HRC/CBERS
images were segmented and classified in order to obtain the land
use and cover map of the urban area of Santa Maria, and the Aster
digital elevation model was used in order to get information about
the study area declivity. The map of hydrologic soil groups was
developed from a map of existent soil types, these ones were
reclassified according to their textural characteristics. For
every combination of hydrological groups and land use and land
cover classes were aggregated values corresponding to its
potential runoff (curve number). Finally, it was done the
integration of this potential runoff map with the declivity
information, in order to identify the most potential areas to
flooding in the urban area of Santa Maria. The application of
curve number model was efficient to get the characteristics of the
runoff and to identify the potential urban flooding areas in the
study area. The satellite images and the GIS were very efficient
tools in the development of the land use and land cover, runoff
and declivity maps.",
